remember when?????

i remember when bart first opened back in the early 70's,there was talk back then of having it go all the way around the bay by 1990, if san mateo &santa clara counties would agree to the tax structure for funding the projects. so what ever happened to all the great hopes & dreams of a bygone era..
then they said to altimont & tracy by 2000. we all see that hasn't happened either, i wonder were all the supposed reserves of financials went over the years. maybe that should be looked into also, what do you think about it all.. leave answers THINK about what was originally planned
